No I didn't misunderstand. I was not referring to the color gamut. This thread is about QC and frankly screen uniformity is a QC issue. The post I referred to flat stated that the screen isn't the main factor and I simply replied that as far as tablets go it most certainly is since that is the part you actually see all the time. Regardless of OS you cannot 'unsee' a screen defect. Even just reading a book can be affected.
Whether a person disagrees with the decision to lower the gamut on the mini it was a specific decision by Apple. It is not a QC issue.
Then you didn't read the rest if my post as it specifically mentions color gamut and screen retention. It's a discussion I was posting to Miss Kitty and you are reading it out of context.
